The phosphate groups in the DNA molecule give it a negative charge.
A polar molecule doesn't necessarily have any overall charge. All polar means is that one part of the molecule has a negative charge and another part of the same molecule has a positive charge. These charges balance. When the charges don't balance and there is a net charge, it is referred to as an ion. An example of a polar molecule is fluoro-methane, or CH3F. The fluorine attracts the electrons in the bond a lot harder than carbon. so the fluorine has a negative charge while the carbon atom ends up with a positive charge.
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.
The oxygen atom in a water molecule is partially negative due to its higher electronegativity compared to hydrogen. This results in a slight charge separation within the molecule, making oxygen slightly negative and hydrogen slightly positive.
Oxidized.Oxidation involves a loss of electrons.The answer above in a general context is wrong I'm afraid - If an atom loses an electron it becomes an ion and the same if it gains one - and electrically charged particle.
Water is a polar molecule, meaning it has a positive and negative side. This allows it to interact with other polar and ionic substances, breaking them apart and forming bonds with the dissolved molecules. This process is known as hydration or solvation.
the electrons and protons of the atoms inside the molecule
A polar molecule doesn't necessarily have any overall charge. All polar means is that one part of the molecule has a negative charge and another part of the same molecule has a positive charge. These charges balance. When the charges don't balance and there is a net charge, it is referred to as an ion. An example of a polar molecule is fluoro-methane, or CH3F.

there is no negative pole in h2o molecule
DNA is negatively charged because it contains phosphate groups in its structure, which have a negative charge. These phosphate groups are part of the backbone of the DNA molecule, contributing to its overall negative charge.
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.

Do you mean the electrons? They have a negative charge
A polar molecule in which there is some separation of charge in the chemical bonds, so that one part of the molecule has a slight positive charge and the other a slight negative charge. A common example of polar molecule is water. The water acts as a solvent for polar molecules. A non-polar molecule has no separation of charge, so no positive or negative poles are formed.
a molecule with a difference in charge. i.e. if it is slightly more negative in one place than another you say it has a dipole. you label it with the greek symbol delta- delta+ the - at the more negative part of the molecule. i am looking at this from a chemistry angle.

electrons = negative charge protons = positive charge neutrons = neutral charge
The polar molecule is one which has partially positive charge at its one part or one element of a compound and partially negative at the other. The partially negative part bearing part have usually high Electronegative atom. On the other hand, the radical is one which bears no charge but it has an unpaired electron.
